A car of mass `m` is driven with acceleration `a` along a straight level road against a constant external resistive force R. When the velocity of the car V, the rate at which the engine of the car is doing work will be

`RV`

`maV`

`(R+ma)V`

`(ma-R)V`

Text Solution

Verified by Experts

The correct Answer is:

`F-R=ma`
`F=R+ma`
`P=Fv=(R+ma)v`
